multi-core processors I5

1. multi-core processors I5
What is a Processor?
The Processor or Central Processing Unit (CPU) component of your PC
that carries out instructions given to
it by your Operating System (Windows.) Think of the processor as a
brain that receives instructions and messages and sends out
instructions to other hardware
What is a Core?
A standard processor has one core (single-core.) Single core processors
only process one instruction at a time(although they do use pipelines
internally, which allow several instructions to be processed together;
however, they are still run one at a time.)
What is a Multi-Core Processor?
A multi-core processor is composed of two or more independent cores,
each capable of processing
individual instructions. A dual-core processor contains two cores, a
quad-core processor contains four
cores, and a hexa-core processor contains six cores.
How many cores do i5’s have ?

2. An i5 processor has 2 or 4 cores (depending on the model you have.)
Why do I Need Multiple Cores?
Multiple cores can be used to run two programs side by side and, when
an intensive program is running, (AV Scan, Video conversion, CD ripping
etc.) you can utilize another core to run your browser to check your
email etc.
Multiple cores really shine when you’re using a program that can utilize
more than one core (called Parallelization) to improve the program’s
efficiency and addressability. Programs such as graphic software, games
etc. can run multiple instructions at the same time and deliver faster,
smoother results.
If you use CPU-intensive software, multiple cores will likely provide a
better computing experience. If you use your PC to check emails and
watch the occasional video, you really don’t need a multi-core
processor.
Intel i5 processor.
History
Third Generation
The core i5 series based on 22 nm microarchitecture provides a top
clocking frequency of 3.8 GHz, with Turbo Boost, along with four
processing threads. These chips are ideally suited for the business
users, who would benefit from the extra multitasking ability.
Second Generation

3. In January 2011, the Sandy Bridge based core i5 line of processors was
released, as an improvement over the earlier generation. This includes
quad core - Core i5-2500, 2500K, Core i5-2xxxT (with dual/quad core)
and Core i5-2xxxS lines of processors with 6 MB of L3 cache, direct
media interface and an integrated GPU. The mobile line of processors
have also been launched in a new Sandy Bridge avatar, in the form of
Core i5-2xxxM, Core i5-2xx7M, with 2 cores and 3 MB of L3 cache. Their
clocking frequency ranges from 1.4 GHz to 3.3 GHz.
First Generation
This family of processors consists of three lines, which include the core
i5 7xx, core i5 7xxS and core i5 6xx series. They have processor clocking
frequencies ranging from 2.4 GHz to 3.33 GHz which can be enhanced
by Intel's new Turbo Boost technology. Some processors have 4 cores
with 4 threads (core i5-7xx and core i5-7xxS Lynnfield series) and some
with 2 cores and 4 threads (core i5- 6xx Clarkdale Series with Hyper-
Threading disabled). Most have an 8MB L3 cache, with LGA 1156
socket, direct media interface and integrated GPU. Besides this, four
separate lines - Intel Core i5-5xxM, Core i5-4xxM, Core i5-5xxUM and
Core i5-4xxUM, with 2 cores and 3 MB L3 cache have been exclusively
created for notebook computers.
Features of i5 processor.
• I5 processors have ability to work with integrated memory and
can enhance the performance of the applications. The increase
the memory up to 1333 MHz
• as I5 processors have high speed performing rate so they are able
to perform at the maximum CPU rate of 3.6 GHz
• turbo technology is present in the device that boost up the
working speed of the computational systems

4. • It provides the 64 bit architecture for the users for the reliable
working.
• Micro architecture for the I5 processors was presented by the
Nehalem and these processors have a cache rate up to 8 MB
• I5 provides the opportunity to the users to use the system with
multi tasking.
• A big feature of the I5 processors is that they have ability to run
two multitasking processors together that are generally called as
dual processors and can increase the working performance of the
system efficiently.
• Turbo boost technology of I5 processors is the key beneficial
feature of the I5 processors that allow the users to do their
regular and important working with the help of heavy
applications.
Available i5 processor.

5. i5 over i3.
• This is the mid-size processor of this bunch, recommended
for those who demand a little speed, but not quite enough
where the user will be able to run intensive applications.
• As with the Core i3 processor, this comes with 2-4 cores,
the main difference is that it has a higher clock speed than
the Core i3.

6. • This is also a heat and energy efficient processor, but it
does seem to be better at this particular job than the Core
i3.
• The number of threads used in this is no different than the
Core i3 with 2-4 threads , it also uses hyper threading
technology for a boost in performance.
• The cache of the Core i5 is bigger than the Core i3.
• The Core i5 is in turbo mode is made available, this
provides users with the opportunity to turn off a core if it’s
not being utilized.
